BEST MODE

(7) Concrete features and other advantages of a three-dimensional advertising device according to the present invention will be more apparent from the following description of preferred embodiments made with reference to the accompanying drawings.

(8) Referring to FIGS. 1 to 3, a three-dimensional advertising device 1 according to the present invention includes a frame 10 configured to have a predetermined shape, a plurality of unit cells 20 arranged on the frame 10 in the form of an X-Y matrix so as to be supported by the frame, and a controller 30 for selectively turning the respective unit cells 20 in response to an external input signal.

(9) The shape of the frame 10 is not particularly restricted, as long as the frame is capable of turnably supporting a cell plate 21 of each of the unit cells 20. For example, the frame 10 may be a quadrangular frame including a back panel (not shown), or may be a frame having a closed rear surface.

(10) Preferably, the front surface of the back panel of the frame 10 is colored with as dark a color as possible, such as black. The reason for this is that, in the case in which the cell plates 21 of the unit cells 20 are turned forwards so as to protrude and are then opened, the opened unit cells 20 are definitely visually distinguished from the surroundings due to the characteristics of the present invention, in which the opened parts constitute three-dimensional advertising content, whereby the advertising content is more clearly expressed.

(11) Each unit cell 20 includes a cell plate 21, which constitutes the front surface of the frame 10 together with adjacent unit cells 20, and an electromagnet 24 for turning the cell plate 21 forwards so as to protrude.

(12) To this end, the upper end of the cell plate 21 is supported at the frame 10 via a hinge 23 such that the cell plate is disposed vertically due to the weight thereof, and the cell plate is provided at the rear surface thereof with a magnet 22, which is opposite the electromagnet 24. The faces of the electromagnet 24 and the magnet 22 of the cell plate 21 that face each other are configured to have the same polarity such that, when electric power is supplied to the electromagnet 24, the cell plate 21 is turned forwards so as to protrude due to the repulsive force between the electromagnet and the magnet.

(13) In order to definitely express and discriminate the advertising content, the cell plate 21 itself or the front surface of the cell plate is preferably made of a reflective plate such that the advertising content formed by the cell plate 21, which is turned and opened, is clearly distinguished from adjacent unit cells 20, which are not opened.

(14) The hinge 23 may be individually applied to each unit cell. Preferably, however, the hinge is configured to turnably support cell plates 21 of all unit cells 20 located in one line at the same time.

(15) An external input device may be connected to the controller 30. The controller controls a power supply device 40 in response to advertising content set by the input device such that predetermined electric power is selectively supplied to the electromagnet of the selected unit cell 20. In addition, the voltage that is applied to the electromagnet 24 of the selected unit cell 20 is selectively adjusted in response to the input advertising content in order to adjust the intensity of the electromagnet 24.

(16) Even in the case in which the unit cells 20 are selected depending on the advertising content, therefore, the turning angles of the cell plates 21 thereof may be the same as each other or may be different from each other, whereby it is possible to express various kinds of advertising content in the present invention, in which the advertising content is expressed based on the turning and opening of the cell plates 21.

(17) Particularly, in the case in which the cell plates 21 that are turned forwards and opened are repeatedly widened or narrowed within a predetermined angular range or in the case in which the same advertising content is alternately or continuously applied to adjacent unit cells 20, it is also possible to dynamically express three-dimensional advertising content just like an LED electric bulletin board.

(18) Meanwhile, for example, as shown in FIG. 1, the three-dimensional advertising device according to the present invention may further include an illumination means 50 disposed at the upper end of the frame 10 for illuminating the unit cells 20 disposed at the front surface of the frame. It is possible to express the advertising content in three dimensions even at night using the illumination means 50. In addition, a color may be applied to the illumination means 50, whereby it is possible to attract people's attention through more improved visibility and more increased distinctiveness.

(19) Another embodiment of a cell plate 25 of the unit cell 20 according to the present invention is schematically shown in FIGS. 4 to 6.

(20) In this embodiment, the cell plate 25 includes a main body 26, the front surface of which is colored with a dark color, and a plurality of blades 27 provided at the front surface of the main body 26 so as to be inclined downwards, compared to the construction of the previous embodiment.

(21) For example, the main body 26 may be configured in the shape of a frame having a back plate 26a, at the rear surface of which a magnet 22 is provided. The upper end of the main body is turnably supported at the frame 10 via a hinge 23, and the front surface of the back plate 26a is colored with a dark color, such as black.

(22) The blades 27 are disposed so as to be spaced apart from each other by a uniform distance in the vertical direction, and are installed so as to cover the front surface of the main body 26 when the cell plate 25 is oriented vertically in the state of not being opened. The front surface of each of the blades 27 is disposed at the front surface of the main body, and is colored with a bright color.

(23) In the case in which no electric power is supplied to the electromagnet 24, the cell plate 25 is oriented vertically by the weight thereof, whereby the dark color thereof is hidden by the blades 27. In the case in which electric power is supplied to the electromagnet 24, however, the cell plate 25 is turned forwards and opened due to the repulsive force between the electromagnet 24 and the magnet 22. The front surface of the back plate 26a of the dark main body 26 is exposed to express advertising content depending on the turning angle of the cell plate.

(24) Even in the case in which the turning angle of the cell plate 25, at which the cell plate protrudes forwards, is not great, it is possible to perfectly express the advertising content. In particular, since the cell plate 25 itself has contrast by which the advertising content is displayed, it is possible to express the three-dimensional effect of the advertising content more clearly and definitely than the previous embodiment.

INDUSTRIAL APPLICABILITY

(25) A three-dimensional advertising device according to the present invention includes a frame 10 configured to have a predetermined shape, a plurality of unit cells 20 arranged on the frame in the form of an X-Y matrix so as to be supported by the frame, and a controller 30 for controlling a power supply device in response to an external input signal to selectively supply electric power to the unit cells such that the unit cells are selectively driven, and each of the unit cells is configured to be operated by a magnet, disposed at the rear surface thereof, and an electromagnet.

(26) As a result, each of the unit cells is turned forwards by the magnet and the electromagnet so as to protrude such that the advertisement is expressed, whereby it is possible to three-dimensionally express advertising content. Consequently, it is possible to obtain an excellent visual communication effect, and at the same time, it is possible to greatly improve visibility and attention-gathering ability, whereby it is possible to maximize an advertising effect.

(27) In addition, it is possible to freely express and change desired advertising content while performing dynamic expression using only a relatively simple structure that is capable of adjusting the intensity of the electromagnet in order to turn each of the cell plates. Therefore, the three-dimensional advertising device according to the present invention has industrial applicability as a practical device that is capable of achieving an excellent advertising effect at low cost.
